Post by waynardHi,I am looking for an owner's manual for this piece. Can anyone herehelp???please email me if you can.tnx

I've used a lot of Yorkville gear, but I don't remember the SP12.Was it one of their early speakers?Mike T.

Sorry, should have read your subject line.Yorkville Audiopro SP-12 powered mixer.Also known as the "MICROMIX" SP12.Are you trying to use it, or to repair it?I have an old catalog that describes it, but no manual.Sorry, no schematic, either, but if you're desperateI might know someone who has the info.There are a few of these still in service out here in thehinterlands of western Canada.The mixer was fairly bullet-proof. The most common failurewas dirty normalling contacts on the 1/4" jacks between themixer and the power amp.Mike T.
